This is not an Ortofon 2M Cartridge, but rather the replacement stylus which you buy to save a little money (and have that much less plastic floating in our oceans).
You need to already own an Ortofon 2M Red cartridge to use this. To install, you remove the old stylus from your existing cartridge, and install this.
